In gas scrubbing applications, the effectiveness of the spray is determined by the size and speed of the droplets. While smaller droplets provide greater reflection, they may not cover all necessary areas, leading to untreated gas escaping and reduced scrubber efficiency. Therefore, a balance needs to be struck between the small droplet size and the achievable spray coverage.
This balance can be achieved through careful nozzle selection. Twisting nozzles are often found to be effective in gas scrubbing applications as they produce fine drops and have a wider range of bead sizes. Although the average drop size is smaller, there are also larger drops that help deliver the entire spray to areas where it would normally be blown off course.
Different nozzle options are available based on the gas flow rate and cooling requirements. For gas extinguish applications, the TF twisting nozzles with a wide range of spray points and flow rates are suitable. The P range of misting nozzles is a good option for low flow rate applications, while the SA range of high flow rate air atomizing nozzles is ideal for mid-sized gas cooling applications that require rapid liquid evaporation.
